hllplieation filed February 19, 1913. Serial l lo. 749,325.

WaIthain, county of Middlesex, Commonwealth of Massachusetts, have invented certain new and useful improvements in ll/latting-Roughing Machines, ofwhich the following. is a specification.

'lhis invention relates to the preparation of straw matting for use in the manufacture of suit cases and other articles of bag gage, and particularly with "a machine for the treatment of the surface of the matting prior to the gluing.

llnthe manufacture of suit cases and the like frcm straw matting, it is advisable to have the matting glued to a backing of. fiber board. The ordinary straw matting of commerce, which is lmown as Japanese or rice straw matting, has a very smooth exterior to which glue will not adhere. This has made it necessary in the practice heretofore to fill the surface of the matting with glue, embedding it between the fibers and about the string warp, in order to get a surface which would adhere to paste boardi l have found that it is possible to slightly abrade one face of the matting, removing the smooth surface from the most exposed .part of the straw woof. ll accomplish this by a sand papering which not only takes oil I the glazed surface of the straw, but roughens the fiber of the straw and leaves it in condition in which it will readily take glue.

The machine consists of a roll upon which a covering of sand paper may be wrapped and across which the web of matting may be drawn while it rotates. Q

The construction and operation of my machine will be more fully described in the specification which follows.

lid

The form which l have shown in the drawings as an illustrative embodiment of my invention is one" which I have found. well adapted to practical use. -lhroughout specification and drawings like reference numerals are employed to indicate corresponding parts, and in the drawings: Figure 1 is a central section of my machine, and Fig. 2 is a transverse view partly in section.

My machine comprises a frame 1 in which is journaled a shaft 2, carrying a roll 3, covered with sand paper or any other suit-' able abrasive. The roll is driven by pulleys 'l in the direction indicated by the arrows,

which is opposite to the movement of the matting M. The rubber lead rolls 5 and 6 are arranged to engage the matting and draw the same pastthe roughening roll 3. An extension frame 7 is mounted on the main frame 1, and in this is pivoted a pressure arm 8, pivoted at 9. The pressure arm 8 has on its under face a pad 10 of felt or like material, for holding the matting against the roll 3. ably mounted in the extension frame 7, having on its under face a series of springs 12 which bear on the arm 8. lhe cross bar 11 is adjustably mounted by screws 13 which are tapped through the cross piece 7 of the frame 7. By the adjustment of these screws 13 the desired pressure of the arm 8 may be secured. On the opposite end of the shaft 2 is mounted a pulley 14 which may be suitably belted to drive the rolls 5 and 6.

in order to get the proper resistance on the matting, l pivot at a point below the roll 3 a stall 15 of larger diameter than the roll of matting so that the roll may play about in the stall as it unwinds. Leading fromthe stall 15 is an upwardly inclined way 16 on which the matting M runs to a point adjacent to the pad 10. The matting is delivered from this run way. 16 to the roll 3 and is drawn to the rolls 5 and 6 beneath the pad 10 and against the rotation of the cylinder 3.

By the proper adjustment of this machine, the matting may be slightly scoured so as to remove the glaze from the exposed woof of straw. When thus ground, the matting may be securely glued without danger of blistering or buckling, and at a saving of about one-half of the glue necessary in the practice heretofore.

Various modifications may obviously be made in the construction and operation of --my device, all without departing from the spiritof my invention if within the limits of the appended claims.

What I therefore claim and desire to secure by Letters Patent is:

1. ll matting surfacing machine comprising a frame, a sand paper roll rotatably mounted in said frame, means for rotating said roll, a hinged presser arm pivoted above said roll, a Dresser pad on said arm, an adjustable follower above said arm, a pair of lead rolls in advance of said sand A cross bar 11 is slidpaper roll andhaving their bite below the me of contact of said sand paper roll, a delivery stall for a roll of matting and larger than the diameter thereof and positioned below the center of said sand paper roll, and an inclined guide from said stall to said sand paper roll.

2. A matting surfacing machine comprising a frame, a sand paper roll rotatably mounted in said frame, means for rotating said roll, a presser arm movably mounted above said roll, a pair of lead rolls. in ad- Vance of said sand paper roll and having their bite below theline of contact of said sand paper roll. andan inclined guide from said delivery to said sand paper roll.

3. A matting surfacing machine comprising aframe, a sand paper roll rotatably mounted in said frame, means for rotating said roll, a hinged presser arm pivoted above said roll, a presser pad on said arm,

an adjustable follower above said arm, a pair of lead rolls in advance of said sand paper roll and having their bite below the line of contact of said sand paper roll and a delivery for a roll of matting and positioned below the center of said sand paper roll.

4. A matting surfacin machine comprising a frame, an abra lng roll rotatably mounted in said frame, means for rotating said roll, a presser movably mounted above said roll and a pair of lead rolls in advance of said sand paper roll and having their bite below the line of contact of said abraf
